No, it was my fault for not including the "open printing" & "close
printing" statements in my original quoted script.

I'll consider this, but at the moment, I cam happy with using
revPrintText.Once I realised what it was doing, I set up a separate
printing field and header & footers and it's working well. I still use
my layout card to set up the print parameters and to act as a preview.

One factor that is turning me away from using a print stack is the
slowness of "print this card". In some rough tests, I found it to take
about 140 ticks per card where revPrintText & revPrintField were
taking 13 - 14 ticks. Once you have more than a couple pages to print,
this speed difference would become significant.

Cheers,
